Problems: This moring after booting up and login to my win8 computer i notice the touch pad with mouse were lagging. Also
i tried to download several software from the web but download icon "Ok" to direct the file location would not light up but stayed shaded. So I could not download the file.

Also at times the I could not minimize with a click in the corner the webpage with mouse or touchpad.

Cursor at time seems stuck.

Laptop is ASUS F550LA-SS71 15.6, i7 intel, Win8.1 64 bit
